My research involves developing models and tools to support architecture-level planning of large software evolutions. Over the past couple of years, we have developed a theoretical framework that we think encapsulates the most important issues in these kinds of evolutions, as well as formal models and tool prototypes within this framework. One important component of our framework involves the f...

One of the most important issues in the management of disasters that caused by natural phenomena in urban areas is how to evacuate inhabitants of hazardous areas to safe areas. Optimal allocation of capacities in safe areas to inhabitants leads to effective decision making by inhabitants for displacement to safe areas in evacuation process. Effective decision making in disaster management is so...

Recently, the World Health Organization (WHO) declared that the spread of polio is an international public health emergency, and a coordinated international response is sought. Although the importance of such a response is recognized, there are challenges to stopping the spread of polio and achieving a polio free world. The most important issue is directing limited national resources to the spe...

When a data mining model is to be developed, one of the most important issues is preserving the privacy of the input data. In this paper, we address the problem of data transformation to preserve the privacy with regard to a data mining technique, associative classification, in an incremental-data scenario. We propose an incremental polynomialtime algorithm to transform the data to meet a priva...
